Definitions

  • the adhesive film spreads unevenly on the at least one substrate because the substrate has at least one microscopic, but occasionally macroscopic, irregularity on its surface to be laminated.
  • the initially substantially uniform film of the adhesive composition becomes an unevenly thick film in which the flowable components of the adhesive composition accumulate in "valleys" of the substrate surface, while the protruding "peaks” or “hills” of the surface structure of the substrate Adhesive is squeezed in the direction of the "valleys". This generally affects the adhesion of the laminate and / or other properties such as the clarity of the transparency of a transparent laminating substrate.
  • 4,830,887 A proposes to connect the film limiting elements as a hollow channel with a longitudinally extending connecting slot to the film from the photographic coating composition and to keep it under reduced pressure in order to extract excess material from the low-viscosity liquid and to be able to reuse it if necessary.
  • Such constructions have proven impractical in the context of heated adhesive compositions, such as hot melt adhesives, which have been pressed out of a slot die under pressure.
  • the application method for dispersions known from WO 98/47 630, such as of aqueous pressure-sensitive adhesives, are also unsuitable for laminating purposes using hot-melt adhesives and the like of comparatively viscous adhesives.
  • This document proposes to inject the lubricity between the suspended low viscosity film and the lateral film confining elements with an auxiliary liquid via a feed channel. Consumables are also lost in the process through such feed liquids.
  • the laminating methods of the invention and the laminating apparatus according to the invention are possible both for the non-contact delivery of the continuous film of the adhesive composition from the delivery device to the substrate, as described, inter alia, in WO96 / 25902 and WO99 / 28048 and other references.
  • Such a product can also be used at any time later to laminate without being provided with a laminating layer, wherein the adhesion mediation is made possible by the adhesive composition on the first substrate. It is also in the nature of the present invention that the film of the adhesive composition at certain points where no adhesive on the substrate is needed to save the adhesive in some areas.
  • the profiling in the left-hand half of the figure is groove-like and in the right-hand half of the figure web-like, with the concrete exemplary embodiment having a kedermé cross-section. to recognize form.
  • the profiling serves to improve the guiding and holding of the lateral edges 3A of a film 3 of a flowable adhesive composition on the film limiting elements.
  • the heat of the heated adhesive composition resulting in the valley-shaped profiling 14 is thus effectively dissipated, so that the adhesion of the film edges of the film of the adhesive composition to the leading edge 14 is sufficient to virtually completely avoid neck-in of the film.
  • another heat exchange flag 15 ' which extends approximately parallel but arranged offset from the film boundary surface 12C and extends in heat-conducting contact with the film boundary surface 12C and optionally further leading edge 14'.

Abstract

L'invention concerne un procédé de stratification dans lequel une composition d'adhésif (8), fluide ou rendue fluide, en particulier un adhésif fondu à chaud, qui provient d'un appareil de revêtement (10) est délivrée sous la forme d'un film (3) sensiblement continu ou perforé par une tuyère à fente (12) dotée de butées latérales pour le film, et est appliquée et fixée sur la surface d'au moins un substrat (1) en forme de bande. Ce procédé permet d'améliorer la régularité du film de la composition d'adhésif en ce que les bords (3A) du film (3) sont guidés jusque sur le substrat (1) par les éléments (12A) de limitation du film en étant serrés ou bordés vers l'extérieur par une fente (12B) de la tuyère et en ce que la chaleur est évacuée dans l'atmosphère ambiante par au moins un élément d'échange de chaleur disposé le long des éléments de limitation du film.
